More isn't always better: Too much calcium has risks. Dietary calcium is generally safe, but more isn't necessarily better, and excessive calcium doesn't provide extra bone protection. If you take calcium supplements and eat calcium-fortified foods, you may be getting more calcium than you realize.
Genetic Recombination in Bacteria. This is a process where genetic materials, contained in two separate genomes, are brought together within one unit. In bacteria the recombination takes place by (1) transformation, (2) transduction and (3) conjugation.
There are three different types of cloning that exist today. These are recombinant DNA cloning, reproductive cloning and therapeutic cloning. Recombinant DNA cloning is a process that involves the transference of a particular DNA fragment from one organism to a self-replicating genetic element.
